What can I use for Drivers in an Sansui AU-417?

[jackson]

My AU-417 had some blown output, I got some NOS for replacements some of the drivers are blown too. They are 2SD382 & 2SB537 neither one of these are on my substitution lists. Can I use A940 C2073 or 15032 15033 ? Can't wait to give it a listen. Thanks Jackson

I think others sugested the TO-126 pair TTA004B and TTC004B. Center pin needs to be soldered to a lug to wire the screw which makes the collector connection. The A940/C2370 are ok except for their transition frequency, being 10 time lower than the original parts, if you care about that.

As Jose said above , it requires modification with the collector pin. The package is
TO-220F, closer to the original package
TO-220.

Digi-Key still has Sanken C4382/A1668. Though the spec sheet shows 15MHz/20MHz minimum, if you look at the curves, they are actually pretty close to D382/B537, and way faster than C2073/A940.
